Reymondia horei is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Paludomidae. This species is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. Its natural habitat is freshwater lakes.

This species co-occurs with, and is sometimes confused with Reymondia pyramidalis . It is, however, a separate species. [2]

Description

The shells of R. horei are composed of six reddish-brown whorls, which are smoothly curved. There is a white band on all whorls. The overall height of the shell ranges from 13 to 16 millimetres (0.51 to 0.63 in), and diameter from 5.9 to 9 millimetres (0.23 to 0.35 in). The visible soft parts of the animal are colored grey or olive green, with a brown foot and white sole. [2]

Habitat

This is a freshwater-adapted species, endemic to Lake Tanganyika. It occurs in depths from 80 to 100 centimetres (31 to 39 in), frequently under rocks. It is most frequently found in the surf zone. It is generally only found on the top side of rocks, but also can be found on sand when there is minimal wave action. [2] The species does appear to segregate by size. [1]

The species is widespread and common, although the most significant threat to its survival is sedimentation of habitat. [1]

Lake Tanganyika is an African Great Lake. It is the second-largest freshwater lake by volume and the second deepest, in both cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo, Burundi, and Zambia—with Tanzania (46%) and the DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.

Beddomeia camensis is a species of very small freshwater snail that is endemic to Australia. The invertebrate is 2-4 mm in size, it is a gastropod mollusk and belongs to the Hydrobiidae family, a large family of freshwater snails recognised by their small size and cosmopolitan distribution. Beddomeia camensis is one of the least populated species within its family distributed across only 5 small to medium-sized streams that flow into the Cam River catchment in North-West Tasmania.

Beddomeia waterhouseae, also known as Claytons Rivulet freshwater snail, is a species of freshwater snail in the family Tateidae. This species is endemic to northern Tasmania in Australia. The holotype specimen was found in a very small tributary of Little Clayton's Rivulet and is held at the Australian Museum. B. waterhouseae is small and as an adult has a shell measuring between 1.7 to 3.7 mm in length. The shell shape is ovate-conic to broadly conic and has a thin inner lip and no columellar bulge. This species feeds on algae and detritus on rocks. The female of the species lay single eggs in capsules made of sand grains and attached to the underside of rocks or wood. B. waterhouseae is considered vulnerable by the IUCN as it has a very small range and is sensitive to water quality and so may be threatened by disturbances of its habitat. Other threats include habitat loss. Conservation activities such as assessment of the aquatic ecosystem and vegetal surveys are being undertaken in an attempt to preserve this species.
